Everyone passes -1 here, including the follow-up patch for cm_t35. Why
do we need the change?
This change is useful because on OMAP it's a fair assumption
that card detect (and write protect) signal will be ascertained via
a GPIO, though it is not a certainty.
Everybody who is not cm_t35 get a -1 because I did not try to
figure out if they really do use GPIOs for card detect.
cm_t35 gets a -1 because it does not use OMAP GPIOs for card detect,
but relies on those of the PMIC instead.
